Changeset 9184:2306d524ec1c --------------------------- Standard Switch: Drain the system before switching CPUs When switching from an atomic CPU to any of the timing CPUs, a drain is unnecessary since no events are scheduled in atomic mode. However, when trying to switch CPUs starting with a timing CPU, there may be events scheduled. This change ensures that all events are drained from the system by calling m5.drain before switching CPUs.
Since m5.changeToTiming() is used by any atomic CPU -> timing CPU switch, tested all combinations of switches with x86. All prior working combinations still work correctly, and this patch enables timing -> detailed switch as necessary for Ruby.
